"I need to grab weather radar data via API, generalize it into fake clouds, place them on a mapbox map, add shadows and an offset so it looks like they're floating above the surface" GPT 5.1 Codex: "That will take months" Gemini 3 Pro: "Sure here you go" ??? I don't get LLMs

Tom Patterson Tom Patterson is right: this is the golden age of cartography. We have infinite data, tools that let you filter terabytes on someone else's computer, and language models to format your queries. I used all that to make a quick retro poster of the Lower 48, something like a 1987 USGS giveaway you’d see on a classroom wall: 1) Google Earth Engine to filter 2013-2024 Landsat 8 scenes, filtered out clouds + cloud-shadows using the "QA_Pixel" band. You get some striping but for this purpose it looks fine. 2) Exported 4x composite images at 1500m resolution, one for each season: autumn, winter, spring and summer 3) Used Eduard to grab a ~300m Mapzen DEM over the continental U.S., cranked up the generalization 4) Match up projections and resolutions in GDAL (went with EPSG:5070, CONUS Albers) 5) Stacked everything in Photoshop, to get that retro look my layers were ordered thus: Levels adjustment layer Imagery layer: 60% opacity, color burn Shaded relief layer underneath 6) Export each to it’s own TIFF 7) Place an Albers raster in a MAPublisher layout, use the MAP View to add my country-outline clipping mask and state boundaries 8) Dupe the MAP Views, replace the geoTIFF with my photoshop output 9) Design work: Franklin Gothic type, added small strokes to the text and blurred the final output a bit to make it look old
